Food Sources

"Greater than 70 percent of a person’s fluoride comes from drinking fluoridated water when they live in a community that fluoridates the drinking water. Other beverages with a high amount of fluoride include teas and grape juice. Solid foods do not contain a large amount of fluoride. Fluoride content in foods depends on whether it was grown in soils and water that contained fluoride or cooked with fluoridated water. Canned meats and fish that contain bones do contain some fluoride. Fluoride content of various foods includes fruit juice, 3.5 fluid ounces, 0.02–2.1 mg; canned crab, 3.5 ounces, 0.21 mg; cooked rice, 3.5 ounces, 0.04 mg; cooked fish, 3.5 ounces, 0.02 mg; and chicken, 3.5 ounces, 0.015 mg."
